We have the first equation: -10x + 5y = zero we can divide all terms by 5 to get: -2x + y = zero This means that: y = 2x .................> equation I
We now will look at the second equation: <span>-4x-6y=54 </span>we will substitute with equation I in this equation to get: <span>-4x-6(2x)=54 -4x - 12x = 54 -16x = 54 x = -3.375
Substitute with the value of x in equation I to get y as follows: y = 2(3.375) = -6.75
Therefore, for the given system of equations: x = -3.375 y = -6.75</span>
